Emotion Dysregulation Moderates the Association Between Stress and Problematic Cannabis Use

The relations of difficulties in emotion regulation and distress intolerance with cannabis problems: The role of protective behavioral strategies underutilization

INTRODUCTION

Difficulties with emotion regulation and distress tolerance are related to more cannabis problems, yet little research has identified why this is the case. Cannabis-related protective behavioral strategies (PBS; behaviors used to mitigate cannabis related problems) are related to less cannabis consumption and related problems. Potentially, these individuals may use cannabis to alleviate the distress and/or in an attempt to regulate their emotions. Thus, the present study aimed to examine the mediational role of PBS on the relations of emotion dysregulation and distress intolerance with cannabis problems.

METHODS

Undergraduate students who endorsed past-month cannabis use (N = 339, Mage = 19.33, SDage = 1.37; 77.9 % female) at a southern United States university completed a survey online via Qualtrics.

RESULTS

More emotion dysregulation and less distress tolerance predicted less PBS use and more cannabis problems, but not cannabis use frequency. After statistically controlling for sex, the relation of each transdiagnostic factor with cannabis problems occurred indirectly via the relations of less PBS use and greater cannabis use frequency CONCLUSIONS: The present study supports previous claims that emotion dysregulation and distress intolerance are related to more cannabis problems. Additionally, results suggest that individuals with high levels of these problems underutilize PBS which, in turn, is associated with more frequent cannabis use and use-related problems. Clinical implications are discussed.

Distress tolerance and problematic cannabis use: does the form of cannabis matter?

BACKGROUND

Low distress tolerance may result in greater vulnerability to problematic cannabis use. However, the role of the primary form of cannabis used has not been examined as a moderator of this association. While marijuana flower remains the preferred form of cannabis, the popularity of other forms of cannabis, including concentrates and edibles, is on the rise.

OBJECTIVES

We examined the association between distress tolerance and problematic cannabis use and whether the primary form of cannabis used moderates this relationship.

METHODS

Participants were 695 (67.6% male) past-month cannabis users who completed an online survey. Multiple linear regressions assessed whether distress tolerance, the primary form of cannabis used, and their interaction were related to problematic cannabis use while controlling for demographic variables and past 30-day alcohol and cannabis use frequency.

RESULTS

Lower tolerance for distress was associated with more problematic cannabis use. Endorsing concentrates as the primary form of cannabis used vs. marijuana flower was related to more problematic cannabis use while reporting edibles as the primary form of cannabis used vs. marijuana flower or concentrates was related to less problematic cannabis use. Individuals preferring marijuana flower or concentrates reported more problematic cannabis use at lower levels of distress tolerance.

CONCLUSIONS

Cannabis users exhibiting low distress tolerance or a preference for concentrates may be at greatest risk for experiencing negative consequences related to their cannabis use. Additionally, building tolerance for stressful situations, among both concentrates and marijuana flower users, may aid in minimizing problematic cannabis use.

Sex Moderates Associations Between Dimensions of Emotion Dysregulation and Problematic Cannabis Use

The current study examined whether sex moderates associations between emotion dysregulation (overall and six dimensions of emotion dysregulation) and problematic cannabis use. 741 adult past-month cannabis users (31.44% female) completed questionnaires on problematic cannabis use (Marijuana Problems Scale) and emotion dysregulation (Difficulties in Emotion Regulation Scale). Mann-Whitney U tests and hierarchical multiple linear regressions were performed. Male cannabis users reported greater difficulties with overall emotion dysregulation, nonacceptance, goals, impulse, strategies, and clarity. Overall emotion dysregulation, nonacceptance, goals, impulse, and strategies were associated with more severe problematic cannabis use, with relationships weaker in female cannabis users. Lack of emotional awareness was associated with less severe problematic cannabis use in male cannabis users only. Examining individual differences in emotion dysregulation as they relate to problematic cannabis use suggests that treatments may need to be tailored for male cannabis users with a focus on specific emotion dysregulation dimensions.

Emotional dysregulation in relation to substance use and behavioral addictions: Findings from five separate meta-analyses

Background/objective

Emotional dysregulation (ED) is a transdiagnostic variable underlying various psychiatric disorders, including addictive behaviors (ABs). This meta-analysis examines the relationship between ED and ABs (alcohol, tobacco, cannabis, gambling, and gaming), and indicators of AB engagement (frequency, quantity/time of use, severity, and problems).

Method

Searches were conducted in PubMed, Scopus, WoS, and PsycINFO. Five separate meta-analysis were run using random-effects models. Moderators (age, sex, continental region, and sample type; community vs. clinical), and publication bias were evaluated.

Results

A total of 189 studies (N = 78,733; 51.29 % women) were identified. ED was significantly related to all ABs. Problems and severity indicators exhibited the largest effects (r's .118-.372, all p <.023). There were larger effect sizes for cannabis problems (r = .372), cannabis severity (r = .280), gaming severity (r = .280), gambling severity (r = .245), gambling problems (r = .131), alcohol problems (r = .237), alcohol severity (r = .204), and severity of nicotine dependence (r = .118). Lack of impulse control exhibited some of the largest effects in relation to ABs. Clinical samples of cannabis users vs. community-based exhibited larger magnitude of associations.

Conclusions

Interventions targeting ABs should address lack of strategies and impulsive behaviors as an emotion regulation strategy specifically, as it is a common risk factor for ABs.

Light Cannabis Use and the Adolescent Brain: An 8-years Longitudinal Assessment of Mental Health, Cognition, and Reward Processing

RATIONALE

For decades, cannabis has been the most widely used illicit substance in the world, particularly among youth. Research suggests that mental health problems associated with cannabis use may result from its effect on reward brain circuit, emotional processes, and cognition. However, findings are mostly derived from correlational studies and inconsistent, particularly in adolescents.

OBJECTIVES AND METHODS

Using data from the IMAGEN study, participants (non-users, persistent users, abstinent users) were classified according to their cannabis use at 19 and 22 years-old. All participants were cannabis-naïve at baseline (14 years-old). Psychopathological symptoms, cognitive performance, and brain activity while performing a Monetary Incentive Delay task were used as predictors of substance use and to analyze group differences over time.

RESULTS

Higher scores on conduct problems and lower on peer problems at 14 years-old (n = 318) predicted a greater likelihood of transitioning to cannabis use within 5 years. At 19 years of age, individuals who consistently engaged in low-frequency (i.e., light) cannabis use (n = 57) exhibited greater conduct problems and hyperactivity/inattention symptoms compared to non-users (n = 52) but did not differ in emotional symptoms, cognitive functioning, or brain activity during the MID task. At 22 years, those who used cannabis at both 19 and 22 years-old n = 17), but not individuals that had been abstinent for ≥ 1 month (n = 19), reported higher conduct problems than non-users (n = 17).

CONCLUSIONS

Impairments in reward-related brain activity and cognitive functioning do not appear to precede or succeed cannabis use (i.e., weekly, or monthly use). Cannabis-naïve adolescents with conduct problems and more socially engaged with their peers may be at a greater risk for lighter yet persistent cannabis use in the future.

Emotion Regulation Moderates Associations between Discrimination and Cannabis Use Patterns among Sexual Minority Young Adult Women

Background

Sexual minority young adults (SMYAs) experience discrimination and have high cannabis use prevalence. Discrimination may be associated with cannabis use, including hazardous use and co-use with tobacco, depending on emotion regulation and gender.

Methods

Fall 2020 survey data assessed discrimination, use frequency of emotion regulation strategies (i.e., cognitive reappraisal, expressive suppression), current cannabis use, hazardous use, and cannabis-tobacco dual use among SMYAs (age 18-34) in 6 United States metropolitan areas (women: n=450, M age =24.1, SD=4.7, 69.6% bisexual, 18.2% lesbian/gay, 12.2% other; men: n=254, M age=24.7, SD=4.5, 33.5% bisexual, 54.3% gay, 12.2% other). Multivariable logistic regression examined the moderating roles of cognitive reappraisal and expressive suppression on associations of discrimination with cannabis use outcomes, stratified by gender and adjusted for age, race and ethnicity, and employment.

Results

Among SMYA women, 89.5% experienced any discrimination; 53.1% reported current cannabis use, of whom 49.4% and 47.7% reported hazardous use and cannabis-tobacco dual use, respectively. Adjusting for sociodemographics, experiencing greater discrimination was associated with greater odds of hazardous cannabis use (aOR=1.08, 95% CI [1.02, 1.15]) and cannabis-tobacco dual use (aOR=1.04, 95% CI [1.01, 1.08]) among SMYA women with greater use of expressive suppression. Among SMYA men, 83.9% experienced any discrimination; 49.2% reported current cannabis use, of whom 55.2% and 44.0% reported hazardous use and cannabis-tobacco dual use. Discrimination and emotion regulation were unrelated to cannabis use outcomes among men. Conclusions: Given high rates of discrimination experiences among SMYAs, emotion regulation skills training may empower SMYAs, particularly women, to cope with discrimination without using cannabis.

Adverse Childhood Experiences and Problematic Cannabis Use: The Role of Emotion Dysregulation and Affective Impulsivity

Problematic cannabis use is highly prevalent among postsecondary students. Consequently, there is a need to examine risk factors associated with problematic cannabis use in this population. The present study investigated whether emotion dysregulation mediates the relationship between adverse childhood experiences (ACEs) and problematic cannabis use, and whether affective impulsivity (negative and positive urgency) uniquely moderates this relationship. Participants consisted of current cannabis users (N = 586) recruited from five universities across Canada. Participants completed an online survey containing self-report measures of ACEs, emotion dysregulation, negative and positive urgency, and problematic cannabis use. Among the sample of postsecondary students, 36% (n = 213) met the threshold for problematic cannabis use. Moderated-mediation analyses revealed that ACEs were positively associated with emotion dysregulation and problematic cannabis use. There was also a significant indirect effect of emotion dysregulation on the association between ACEs and problematic cannabis use at moderate and high (but not low) levels of negative urgency, and at moderate and high (but not low) levels of positive urgency. The moderated-mediation models remained significant when controlling for other facets of impulsivity. Results suggest that elevated levels of emotion dysregulation and urgency are important proximal risk factors for problematic cannabis use among postsecondary students with a history of ACEs. While ACEs cannot be modified given their occurrence in the past, interventions that aim to build mindfulness and adaptive emotion regulation skills may be beneficial for reducing the likelihood that these students will engage in impulsive behaviors, such as cannabis use, when experiencing emotional distress.

Impacts of difficulties with emotion regulation on the longitudinal relationship between peer victimization and changes in adolescent nonsuicidal self-injury

INTRODUCTION

Research has found that peer victimization is associated with adolescent nonsuicidal self-injury (NSSI) behavior; however, most of these studies ignored the association between these constructs at the within-person level. Additionally, the association between peer victimization and NSSI may vary among adolescents with different personal characteristics. With a longitudinal design, this study investigated whether and how emotion regulation (ER) difficulties moderate the relationship between peer victimization and changes in NSSI, with particular attention given to the unique moderating role of different dimensions of ER difficulties.

METHODS

The study sample comprised 3,561 adolescents aged between 10 and 17 years old (Mage  = 13.22, SD = 0.85; 56.9% males). Self-report assessments were administered in December 2021 and June 2022 in Shanxi province, China.

RESULTS

The latent change score model showed that the adolescent NSSI increased during our assessments, with peer victimization as a significant predictor. ER difficulties moderated the association between peer victimization and NSSI changes, but interestingly, in an unexpected pattern. Specifically, peer victimization significantly predicted NSSI changes among adolescents with low ER difficulties but not for those with high ER difficulties. Moreover, among the multiple dimensions of ER difficulties, only nonacceptance of emotional responses and limited access to emotion regulation strategies interacted with peer victimization to predict NSSI changes and showed interaction patterns similar to those at the overall level of ER difficulties.

CONCLUSIONS

The current study revealed the moderating role of ER difficulties in the relationship between peer victimization and changes in NSSI. These findings provide intervention implications for adolescents who engage in NSSI.

Emotion dysregulation in relation to cannabis use and mental health among young adults

BACKGROUND

Emotion dysregulation (ED) is a transdiagnostic variable that accounts for the onset and maintenance of mental health disorders. The interplay between ED, cannabis use and mental health has not been appraised in the young adult population and whether there are sex-dependent effects has yet to be examined. This study looked at whether ED mediates the association between past-month cannabis use and mental health, while considering sex as a moderator.

METHODS

2,762 (64.2% women) undergraduate Spanish students completed an online battery. Among others, they fulfilled the Depression Anxiety Stress Scale-21 (DASS-21) and the Difficulties in Emotion Regulation Scale (DERS-28). A two-way ANOVA assessed the effects of sex and past-month cannabis use on participants' DASS-21 scores. A set of moderated mediations tested whether the indirect effect of past-month cannabis use on DASS-21 through DERS differed by sex.

RESULTS

Past-month cannabis female users showed higher levels of depression, anxiety and stress (M = 51.10, SD = 26.72) than did men [(M = 33.76, SD = 20.31); F(1, 2758) = 5.119, p =.024, η²p =.002]. In female young adults only, the effect of past-month cannabis use on mental health was mediated by ED (total score), non-acceptance of emotional responses, lack of emotional control, difficulties in engaging in goal-directed behavior, and lack of emotional clarity (all p's < 0.005) CONCLUSIONS: Findings indicate the importance of considering ED in assessment and intervention practices. Interventions targeting ED may be particularly effective for female young adult cannabis users.

A Scoping Review of Risk and Protective Factors for Negative Cannabis Use Consequences

Objective

Numerous reviews have examined risk and protective factors for alcohol-related negative consequences, but no equivalent review of risk and protective factors exists for cannabis-related negative consequences (CRNCs)-a gap filled by the present study. This scoping review examined survey-based research of risk and protective factors for CRNCs such as neglecting responsibilities, blacking out, or needing more cannabis.

Methods

Three databases (PubMed, PsycINFO, and Google Scholar) were searched for peer-reviewed manuscripts published between January 1, 1990, and December 31, 2021. A qualitative synthesis was performed using the matrix method and the results were organized using the socioecological model as a framework.

Results

Eighty-three studies were included in the review. There was considerable variation in measures and operationalizations of CRNCs across studies. Risk factors were identified in the intrapersonal (depression, social anxiety, PTSD, impulsivity, sensation seeking, motives, expectancies), interpersonal/community (trauma, victimization, family and peer substance use, social norms), and social/policy (education, employment, community attachment, legalization, availability of substances) domains of influence. Protective behavioral strategies were a robust protective factor for CRNCs. Males consistently reported more CRNCs than females, but there were no differences observed across race.

Conclusions

Future research should identify person- and product-specific patterns of CRNCs to refine theoretical models of cannabis misuse and addiction. Public health interventions to reduce the risk of negative consequences from cannabis should consider utilizing multilevel interventions to attenuate the cumulative risk from a combination of psychological, contextual, and social influences.

The relationship between adolescent emotion dysregulation and problematic technology use: Systematic review of the empirical literature

BACKGROUND AND AIMS

We aimed to systematically identify, evaluate and summarize the research on adolescent emotion dysregulation and problematic technology use. We critically appraise strengths and limitations and provide recommendations for future research.

METHODS

We followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and conducted a systematic review of published original reports on adolescent emotion dysregulation and problematic technology use published until March 1, 2022. A thorough search preceded the selection of studies matching prespecified criteria. Strengths and limitations of selected studies, regarding design and reporting, were identified based on current best practices.

RESULTS

39 studies met inclusion criteria. All of these studies provided on the relationship between adolescent emotion dysregulation and problematic technology use severity based on self-report data.

DISCUSSION

There was a positive correlation between adolescent emotion dysregulation and the severity of problematic technology use. Beyond this, other variables (such as anxiety, depression, self-esteem, etc.) were also closely related to emotion dysregulation and problematic technology use. Such studies are of importance to better understand cause-effect relations regarding both variables.

Intersection between social inequality and emotion regulation on emerging adult cannabis use

Emerging adulthood (EA; ages 18-25) is characterized by socioemotional and neurodevelopmental challenges. Cannabis is a widely used substance among EAs, and hazardous use may increase risk for sustained use patterns and related health consequences. Research shows differential increases in hazardous use by objective as well as subjective measures of social inequality, with more concerning trajectories for youth with greater experiences of social inequality. Learning how to flexibly monitor and modify emotions in proactive ways (i.e., emotion regulation) is a central developmental task navigated during the EA window. Challenges to and with emotion regulation processes can contribute to the emergence of mental health symptoms during EA, including hazardous cannabis use. In this perspective, we highlight emotion dysregulation and social inequality as two critical factors that interact to either buffer against or exacerbate cannabis use during the EA period, noting critical gaps in the literature that merit additional research. We recommend novel methods and longitudinal designs to help clarify how dynamic cognition-emotion interplay predicts trajectories of negative emotional experiences and cannabis use in EA.
